Guitar Amplifier Chassis Housing. The Solid Metal dual-tube distortion
pedal produces massive, face-melting gain. Flexible controls let you
dial in metal tones from the 80's to beyond tomorrow. The unique shape
of the Bass control adjusts the speaker's resonant response for the
proper level of chest-thump during tight palm-muted passages, while the
Scoop and Treble knobs sculpt and top off your tone to perfection.
